v Be it known that we, GEORGE WILLIAM HAWKsLEr and MATTHEW WILD, of Sheiiield, England, have invented an Improved Combination of Furnace and Steam-Generator; and the followingis a full description of the same.

Our invention consists in an arrangement and construction of furnace to be applied to thctubes or'internal parts of boilers now used for generating steam or other water-jackets. Y

This novel arrangement is to" be employed for various purposes, such as paddling and boiling metals, or for boiling or heating other materials or substances, the lue or internalarrangement ofthe boiler or the weten jacket being constructed andadapted to the various dimensions necessary to receive such furnaces, Whichere so arranged that the variou'sfoperations for which they may be required can be eii'ected conveniently from the outside. For example, to adapt a furnace for the purpose of'puddling and simultaneouslyv generating steam in the boiler, the furnace would be so constructed that the portion or-spacc behind the bridge may be rendered available for such purpose, for which object two openings would be made inV the side of the boiler, instead of one opening at the end, as usual. One of these openings would be made in front of the bridge, and communiv` cates with the furnace for supplying fuel thereto, and the other would be made at a point behind the bridge of the furnace, and communicateswith the space or chamber containing the metal to lbe puddled, and through which opening the said operation would be carried on, lthrough which any other required operation may be con ducted, ooth openings being closed by doors, if necessary.

The nature and chief feature ofthe invention being lthe peculiarv adaptation and combination of furnaces with boilers, so that the heat fromsuch furnaces may besimultaneously available for boiling or heating metals, (or for boiling or heating other materials,) and for generating steam in the boiler containing the furnace, for which purposes thcfu'ruace and boiler are peculiarly constructed, as before described.

Secondly, our invention'conslsts in an arrangement of tubes placed under the bottom or side plates (or both) of' the puddlingcliamber of the furnace, through which water circulates, such arrangement being employed and designed to regulate the temperature ofthe said plates, the Water beiug'supplied to the pipes from any cold water tank, and is caused to pass through the` tubes by pressure in any ordinary manner.

In order that the invention may be better understood and explained itiv detail, we have hereunto attached a sheet of drawings, made upon a scale of about one-half inch to the foot.

' Figure 1 represents a longitudinal sectional elevation of a steam-boiler or generator. To the Hue, or internal portion thereof, the paddling or metal-boiling furnace is shownapplied. This view illustrates moreparticularly the peculiar arrangement' and adaptation of a paddling-furnace to the internal portion of the boiler;

Figure 2 represents a transversesection of the same through the4 line A B.

Figure 3 represents an example lof' the same principle of combining boiler and furnace together. lin-these arrangements the boiler is supplied with two furnaces, butiono only may be used if required.

' Figure 4 being a transverse seetionvof the s ame, taken below lthe bridge, through the line-[2G D;

We vwould here remark that these figures and views are only shown as examples, as the combination of a pnddling-furnace with a steam-boiler may be arranged in various ways, the arrangement here shown being also ad'aptedfor the purpose of heu-ting long bars of metal.

In the various figures, a ais the outer shell of the boiler, and IJ b the main furnace, which is constructed and adapted for the purpose of puddling, boiling, or heating metal, and simultaneously generating steam. The fuel is fed into the furnace below the. bridge through the door c in the front of the-boiler, and the opening d communicates with the space or chamber e, containing the metal tobe puddled or heated, through which openi ing or tube the ingots are passed, and the operation of paddling is to be carried on, or through which any other similar operation may be effected. The. gases or products of combustion escaping fromthe paddling-furnace pass through the Hue g, which may either be constructed as shown in fig.1, or such dues may be elongated, and having a diminishing diameter, and extending beyond the furnace.

The bottom and vsides or bottom. of the furnaces or puddling-chnmbersl muy besupplied with series of serpentinel pipes,through,which cold water is causedto circulate by pumps or, otherwise, for lthe purpose of regulating the temperature of 4they plates composing. the sides orbottorn of the furnace, as before described.

'lhis arrangement of furnace, as shown' near the line C D, is constructed more particularly for` the purpose of heating bars or lengths ofmetal which are passed Ainto the chamber-or receptacle through the opening h, at the back of the boiler, the furnace z' being only a. slow-tire furnace to maintain the heat at the end of the chamber.

'Having-now descrbed-the said invention, we wish it to be understood that we claim- The furnace e and boiler a, constructed ns described, the former being located within the latter, in such manner as to be wholly surrounded by water,f'the arrangement being such that the heat of the furnacegenerates the steam of the boiler, as shown and described.v

vIn testimony whereof, we have signed ourfnumes to this specification Iin the presence of two subscribing` witnesses. Gr. W. HAWKSLEY,

MATTHEW WILD.
